Area of Science:

  • Medical Imaging
  • Human-Computer Interaction
  • Surgical Technology

Background:

  • Touchless interaction devices are gaining traction for intraoperative imaging.
  • Limited guidance exists on selecting appropriate touchless mechanisms for operating rooms.

Purpose of the Study:

  • To evaluate the efficiency, accuracy, and surgeon satisfaction of hand motion versus body motion for intraoperative image interaction.
  • Compare two leading touchless interaction mechanisms: hand motion and body motion.

Main Methods:

  • Ten surgeons performed five image manipulation tasks (step-through, pan, zoom, circle measure, line measure).
  • Tasks were executed using three input devices: Microsoft Kinect (body motion), Leap Motion (hand motion), and a standard mouse.
  • CT images were displayed and manipulated using the TedCas plugin for ClearCanvas DICOM viewer.

Main Results:

  • Leap Motion demonstrated comparable accuracy to Kinect for most tasks but had a higher error rate in step-through.
  • Leap Motion significantly reduced task completion time compared to Kinect.
  • Surgeons expressed a preference for Leap Motion, particularly for measurement-intensive tasks.

Conclusions:

  • Hand tracking devices, exemplified by Leap Motion, are recommended for intraoperative imaging manipulation requiring high precision.
  • Hand motion interaction shows promise for enhancing surgical workflow efficiency and accuracy in image-guided procedures.
